Currently, right-clicking on a file in the unstaged area shows a menu where the first entry is "Stage File" but the second one is "Discard Changes":

I understand that "Discard File" could wrongly give the impression that it would delete the file*, but on the other hand it makes it ambiguous whether the action would apply only to this file or to the entire working directory. Maybe it's a silly concern, but for destructive actions, I prefer to be safe than sorry 😅

So what about something like "Discard changes to this file", or "Discard File Changes"? (I personally prefer the former.)

_{* That should probably be an additional option here as well, since in this case it's a new file altogether — or alternatively, adding it to the .gitignore list.}
